CTNF 18/684,242 CTNF 64627 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Priority 02-26 AIA Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statement filed 2/16/2024 has been considered by the examiner. Drawings The drawings filed 2/16/2024 are approved by the examiner. Claim Rejections - 35 USC § 102 07-07-aia AIA 07-07 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – 07-08-aia AIA (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. 07-15 AIA Claim s 1, 9 and 10 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Liu (CN 112393691 A) . With respect to claim 1, Liu discloses: A light-emitting device [ taught by figure 11 ] comprising: a light-emitting unit that emits light for ranging [ taught by light source (31) ] ; a light-receiving unit that receives light emitted from the light-emitting unit [ taught by photodetector (34) ] ; and a control unit [ taught by processor (70) ] that calculates a target value of a driving current of the light-emitting unit on the basis of a light-receiving signal by the light-receiving unit [ page 13 of the translation states, “…The processor 70 may also control the light source 31 based on whether the light source 31 is in a constant power operating state and/or whether the diffuser 33 is in a normal operating state. Specifically, when the detecting electric signal is equal to the first electric signal or located in the first electric signal range, the processor 70 for controlling the driving light source 31 light emitting driving circuit still to drive the light source 31 to emit light at the current working current…” ] and causes the light-emitting unit to emit light by a driving current according to a corrected target value obtained by correcting the target value on the basis of a difference in basic irradiation light amount from a calculation light emission period, during which the light-emitting unit is caused to emit light for calculating the target value [ page 13 of the translation states, “…when the detecting electric signal is equal to the second electric signal or located in the second electric signal range, the processor 70 can control the driving circuit to improve the working current to drive the light source 31 to emit light, so that the light source 31 output power is kept at the target power…” ] , when the light-emitting unit is caused to emit light with a different basic irradiated light amount from the calculation light emission period [ met by controlling the drive current to correspond the detected second electric signal range ] . With respect to claim 9, Liu disclose: A ranging device [ taught by abstract and figure 11 ] comprising: a light-emitting unit that emits light for ranging [ taught by light source (31) ] ; a ranging unit that measures a distance to an object by receiving light emitted from the light-emitting unit and reflected by the object [ taught by photosensitive unit (42) in figure 4; page 5 of the translation states, “…The photosensitive element 42 is used for only receiving the optical signal which passes through the lens assembly 43 and the wave band is 1350nm to 1550nm. based on time of flight (Time of Flight, TOF) technology to obtain depth information of the depth information of the measured object in the light emitting module emits the optical signal of the wave band is generally 850nm or 940nm…” ] ; a light-receiving unit that receives light emitted from the light-emitting unit [ taught by photodetector (34) ] ; and a control unit [ taught by processor (70) ] that calculates a target value of the driving current of the light-emitting unit on the basis of a light-receiving signal by the light-receiving unit [ page 13 of the translation states, “…The processor 70 may also control the light source 31 based on whether the light source 31 is in a constant power operating state and/or whether the diffuser 33 is in a normal operating state. Specifically, when the detecting electric signal is equal to the first electric signal or located in the first electric signal range, the processor 70 for controlling the driving light source 31 light emitting driving circuit still to drive the light source 31 to emit light at the current working current…” ] and causes the light-emitting unit to emit light by a driving current according to a corrected target value obtained by correcting the target value on the basis of a difference in basic irradiation light amount from a calculation light emission period, during which the light-emitting unit is caused to emit light for calculating the target value [ page 13 of the translation states, “…when the detecting electric signal is equal to the second electric signal or located in the second electric signal range, the processor 70 can control the driving circuit to improve the working current to drive the light source 31 to emit light, so that the light source 31 output power is kept at the target power…” ] , when the light-emitting unit is caused to emit light with a different basic irradiated light amount from the calculation light emission period [ met by controlling the drive current to correspond the detected second electric signal range ] . Claim 10 is taught by the abstract . Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim s 2-8 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. 07-100 AIA Any inquiry concerning this communication should be directed to MARK HELLNER at telephone number (571)272-6981 . Examiner interviews are available via a variety of formats. See MPEP § 713.01.
